Question:
I’m trying to add multiple csv-imported lists to a remote executed PS script. It works fine when I pass only one list using the following command:
|
1 2 |
Invoke-Command -filepath $createSAPSPath -ConnectionUri $uri -Credential $credential -ArgumentList (,$accountsList) |
What would be the correct syntax for multiple list objects? I’ve tried:
|
1 2 |
Invoke-Command -filepath $createSAPSPath -ConnectionUri $uri -Credential $credential -ArgumentList (,$accountsList),(,$groupsList) |
But it doesn’t seem to work…
Thanks,
Glenn
Answer:
You have to realize why you need unary comma in the first situation, to understand why its not needed in the second one.
Parameter -ArgumentList takes Object[] argument type. If you are passing single collection, you need to prevent PowerShell from treating single argument (that happens to be a collection) as collection of arguments passed to this parameter.
If you pass something that is collection already (e.g. $AnyObject, $EvenCollection), regardless of the type of individual objects, PowerShell will do what users usually expect: pass first collection to first parameter, second collection to the second parameter.
To sum it up: you should be able to run this like that:
|
1 2 |
Invoke-Command -filepath $createSAPSPath -ConnectionUri $uri -Credential $credential -ArgumentList $accountsList, $groupList |
… and get expected results.
